Ecosystem monitoring information collected in Hanna Shoal in the Chukchi Sea for the COMIDA CAB project from August 2012 to August 2013 (NCEI Accession 0123220)

This accession contains physical, chemical, and biological data collected during research cruises for the Hanna Shoal Ecosystem Study. The study occurred at 138 stations in the Hanna Shoal area of the Chukchi Sea in August of 2012 and 2013, and involved sensor measurements and sampling of water, sediment, and biota conducted by investigators from several universities and research organizations. The dataset includes more than 50,000 data values across 200+ variables, 400+ taxonomic names, 30+ collection methods, and 30+ lab analysis methods. Seawater samples include variables such as salinity, chlorophyll a, particulate organic carbon, total suspended solids, and dissolved oxygen. Samples from the benthic zone include variables such as taxonomic counts, biomass, organic contaminants, and stable isotopes. Sediment samples include variables such as hydrocarbons, metals, grain size distribution, oxygen uptake, and carbon to nitrogen mass ratio. All samples include numerical data value, date of sample collection, location in latitude and longitude coordinates, station identifier, sampling method, and the researcher responsible for the measurement. Furthermore, these data were harmonized according to a community driven set of controlled vocabularies for variable names, chemical speciations, units of measure, sample mediums, and sample types maintained by the Consortium of Universities for the Advancement of Hydrologic Science, Inc. The data are accompanied by an entity relationship diagram and data dictionary explaining the data structure.
